如何使用 pymongo 手动创建 DBRef？
我想手动创建一个 DBRef，以便可以向其中添加一个附加字段。但是，当我尝试传递以下内容时：
{'$ref': 'projects', '$id': '1029412409721', 'project_name': 'My Project'}
Pymongo raises an error:
pymongo.errors.InvalidName: key '$id' must not start with '$'
It might not be the pymongo Reserve the $ for thespecial key，这让我想知道是否可以做我想做的事情想做什么？
I want to create a DBRef manually so that I can add an additional field to it. However, when I try to pass the following:
{'$ref': 'projects', '$id': '1029412409721', 'project_name': 'My Project'}
Pymongo raises an error:
pymongo.errors.InvalidName: key '$id' must not start with '
It would seem that pymongo reserve the $ for the special key, leading me to wonder if it is even possible to do what I'm trying to do?

可能不想像这样手动创建它们，因为 DBRef 中的键需要排序。我们可以添加一个选项来创建带有自定义 kwargs 的 DBRef 实例，这将解决您的问题。如果您为此提交一个 jira，我们应该能够在即将发布的版本中将其发布。
Probably don't want to be creating them manually like that, since keys in DBRefs need to be ordered. We could add an option to create a DBRef instance w/ custom kwargs though, which would solve your problem. If you file a jira for this we should be able to get it out in an upcoming release.
